Hereinafter, specific aspects of a sanitary tissue paper storage container according to an embodiment of the present invention will be described in detail with reference to Fig. 1 to Fig. 8. However, the technical scope of the present invention is not limited to the illustrated examples.
In the following description, the X-axis, Y-axis, and Z-axis as well as the front-rear, left-right, and up-down directions are defined as shown in Figures 1 to 8. That is, in the sanitary tissue paper storage container 100, the side from which the sheets of sanitary tissue paper P are taken out is the top, the opposite side is the bottom, the front side in a plan view of the sanitary tissue paper storage container 100 is the front, the opposite side is the rear, the right hand side when the front surface of the container is viewed from the front is the right, and the left hand side when the front surface of the container is viewed from the front is the left, and the axis along the front-rear direction is the X-axis, the axis along the left-right direction is the Y-axis, and the axis along the up-down direction is the Z-axis.

[First embodiment]
As shown in Figure 1, the sanitary tissue paper storage container 100 of the first embodiment is configured to include a bottomed cylindrical container body 1 for storing sanitary tissue paper P inside, a lid body 2 that can be freely attached and detached to cover the opening of the container body 1, and a removal section 3 that is attached approximately in the center of the lid body 2 when viewed in a plan view.
Since the lid body 2 is configured so as to be freely attached and detached to the container body 1, the sanitary tissue paper P can be stored in and removed from the container body 1 with the lid body 2 removed from the container body 1.

[Hygienic tissue paper]
The sanitary thin paper P is, for example, a roll of wet wipes or wet tissues, and is stored in a rolled state along the Z-axis direction (height direction) in the container body 1. The sanitary thin paper P is perforated at regular intervals along its length, and the user uses the sheets that are cut off along the perforations.

In the following, we will explain the case where the roll-shaped sanitary thin paper P is pulled out from the center side of the roll, but this is not limited to this, and the sanitary thin paper P may also be pulled out from the outside.
Furthermore, the sanitary tissue paper P is not limited to being wound in a roll, but may be a so-called pop-up type in which the tissue paper is stacked in an alternating folded state and is configured so that when one sheet is pulled out, the next sheet is also pulled out.
Moreover, the sanitary tissue paper P may be a wet sheet or a dry sheet.

[Container body]
As shown in Figures 1 to 3, the container body 1 is a container for storing sanitary tissue paper P, and is formed in a cylindrical shape with a bottom and an opening on the top. Also, as shown in Figure 2, a female screw portion 11 is provided on the inner side of the side surface along the circumferential direction from the top end.

The container body 1 is integrally formed by injection molding, blow molding or the like using, for example, PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), ABS (Acrylonitrile Butadiene Styrene) resin or the like.
The container body 1 is preferably circular in plan view with a diameter of 60 mm to 250 mm, more preferably 65 mm to 235 mm, and is formed into a cylindrical shape with a diameter of preferably 175 mm to 200 mm, more preferably 175 mm to 185 mm in the Z-axis direction (height direction), and a thickness of each side of preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

[Lid]
As shown in FIGS. 1 and 2, the lid 2 is composed of a lid main body 21 and a small lid 22 .

(Lid body)
The lid body main body 21 is integrally formed by injection molding, blow molding, etc. using, for example, PE, PP, PET, ABS resin, etc., and has a cylindrical shape with an open bottom surface, and is provided with a top surface portion 21a, a side surface portion 21b, a recess 21c formed in a concave shape facing downward on the inner circumference side of the top surface portion 21a when viewed in a plan view, a hole portion 21d, a main body side wall portion 21e that is cylindrically shaped and stands within the recess 21c to surround the hole portion 21d, and a finger insertion portion 21f.
The lid body 21 is preferably 60 mm to 200 mm in diameter, more preferably 65 mm to 110 mm, in a plan view, and is formed so that the top surface is very slightly smaller than the inner diameter of the container body 1. Also, the lid body 21 is preferably 15 mm to 50 mm, more preferably 33 mm to 45 mm in the Z-axis direction (height direction), and is formed into a cylindrical shape with each surface having a thickness of preferably 0.05 mm to 10.00 mm, more preferably 0.10 mm to 5.00 mm.

(Top surface)
As shown in Figs. 1 and 2, the top surface 21a is the outer peripheral portion of the upper surface of the lid main body 21 formed in a cylindrical shape, excluding the recessed portion 21c and the finger insertion portion 21f.

(Side part)
As shown in Figs. 1 and 2, the side surface portion 21b is a portion that forms a side surface of the lid body 21 that is formed in a cylindrical shape.
An external thread portion 211 that screws into the internal thread portion 11 of the container body 1 is provided on the outer surface of the side surface portion 21b. As a result, the container body 1 and the lid body 2 have a detachable connection structure via the internal thread portion 11 and the external thread portion 211, as shown in FIG.

(recess)
The recess 21c is formed so that its shape in plan view is approximately the same as that of the small lid 22 when closed, and so that the small lid 22 can be fitted in. However, the front end of the recess 21c is larger than the small lid 22 in plan view, and so that a slight gap remains even when the small lid 22 is fitted in, and this gap can be used to hook a finger on the small lid 22 and open it.

(Hole)
Hole portion 21d is a hole that leads to the inside of container body 1 and is formed in a circular shape in a plan view at approximately the center of lid body main body 21 in a plan view. In a plan view, hole portion 21d is formed to be slightly smaller than removal portion 3, and removal portion 3 is fixed to hole portion 21d as described below.

(Main body side wall)
The main body side wall portion 21e is formed within the recess 21c so as to extend upwardly to form a cylindrical shape and to surround the hole portion 21d, so that its outer diameter is the same as or very slightly smaller than the inner diameter of the small lid side wall portion 22a formed on the small lid 22.

(Finger insertion area)
The finger insertion sections 21f are recesses formed, for example, at two locations facing each other across the center of the top surface section 21a, and are formed to a size large enough for the user's fingertips to fit therein.
The user can insert his/her finger into the finger insertion portion 21f and apply a downward pressing force in the Z direction while rotating the lid body 2 in a circumferential direction, thereby screwing the lid body 2 into the container body 1 by screwing the female threaded portion 11 and the male threaded portion 211.

(Small lid)
The small lid 22 is integrally formed by injection molding, blow molding, or the like using, for example, PE, PP, PET, ABS resin, or the like, and has a small lid side wall 22a that protrudes from the bottom surface when closed. The small lid 22 is formed so that its shape in a plan view when closed substantially matches that of the recess 21c, and can be fitted into the recess 21c when closed.

(Small lid side wall)
The small lid side wall 22a is formed in a cylindrical shape that extends downward when the small lid 22 is closed. The small lid side wall 22a is formed so that its inner diameter is the same as or slightly larger than the outer diameter of the main body side wall 21e. The small lid side wall 22a is adapted to come into contact with the upper surface of the recess 21c when the small lid 22 is closed. This allows the small lid side wall 22a and the main body side wall 21e to fit together when the small lid 22 is closed, thereby maintaining the airtightness of the space surrounded by the small lid side wall 22a and the main body side wall 21e, and thus the interior of the container body 1 that is connected to the space via the hole 21d.

In this embodiment, the container body 1 is configured to maintain airtightness inside by fitting the main body side wall 21e and the small lid side wall 22a together, but a different configuration from the above is also possible as long as the container body 1 can maintain airtightness inside.

[Removal section]
The removal portion 3 is an elastically deformable member formed in a generally cylindrical shape that is circular in plan view, as shown in Figures 3 and 4. Figure 4 is a bottom view of the removal portion 3, showing the removal portion 3 of Figure 3 as viewed from below.
Specifically, the removal portion 3 comprises a recess 31 having an inner bottom surface 3a formed in the center when viewed from above, a constricted portion 32 formed on the side, an removal hole 33 formed approximately in the center of the recess 31 (inner bottom surface 3a) when viewed from above, and a chamfered portion 34 formed by chamfering the peripheral portion of the removal hole 33 on the lower surface 3b.
The thickness R1 (see FIG. 5) in the Z-axis direction below the narrowed portion 32 in the removal portion 3 (the dimension between the inner bottom surface 3a and the lower surface 3b) is set to 1.0 mm to 5.0 mm, preferably 1.5 mm to 3.0 mm.

(recess)
The recess 31 is formed on the upper surface of the extraction portion 3 so as to be concave downward in a circular shape in a plan view, leaving a peripheral edge portion. The recess 31 is also formed so that its inner bottom surface 3a is flat.

(Constricted part)
The constricted portion 32 is formed in a radially recessed groove shape so as to go around the circumferential direction approximately at the center in the up-down direction of the side surface of the removal portion 3 and to have a depth in plan view of at least 1/20 and at most 1/10 of the diameter of the removal portion 3. As described above, the removal portion 3 is formed slightly larger than the hole portion 21d in plan view, so that the removal portion 3 can be fixed to the lid body 21 by fitting the edge of the hole portion 21d into the constricted portion 32.

(Extraction hole)
The removal hole 33 is a hole for removing the sanitary tissue paper P stored inside the container body 1, and holds the sheet inserted from the bottom surface 3b side in a state in which its tip protrudes from the upper surface of the removal section 3 (the inner bottom surface 3a of the recess 31).

(Notch)
The extraction hole 33 is formed by a cut portion 330 in the form of two straight lines intersecting in a cross shape at approximately the center of the extraction portion 3 in a plan view.
As shown in FIG. 4, the notch 330 has, for example, four straight portions 331, a first circular portion 332 provided at the portion where the first ends of the straight portions 331 intersect, and a second circular portion 333 provided at the second ends of the straight portions 331 and having a smaller diameter than the first circular portions 332.
The total length of the cutout 330 is set to 5 mm to 30 mm, preferably 10 mm to 15 mm, and is set to, for example, about 15 mm, which is greater than the width of a typical user's index finger. By forming the cutout 330 as a cross-shaped cut in this way, the cutout 330 can more reliably hold the sheet.
The diameter of the first circular portion 332 is set to 2.5 mm to 4.0 mm, and by providing the first circular portion 332 in this manner, the width of the sheet that is gripped by the take-out portion 3 after the sheet is taken out can be made longer. Also, by providing the second circular portion 333, the sheet can be taken out with less force.

Note that while FIG. 5 shows an example in which the extraction hole 33 is formed in a cross shape, the shape of the extraction hole 33 is not limited to this, and any shape can be selected as long as it can perform the above-mentioned function. In other words, radial cuts may be formed by three or more linear cuts. Furthermore, the extraction hole 33 may be formed by a single linear cut, or may be in the shape of a circle, an ellipse, an approximately star, or the like.

The above-mentioned removal portion 3 must be capable of being inserted into the hole portion 21d and must not come off the lid body 21 when the sanitary tissue paper storage container 100 is in use.In addition, since it is necessary for the sheet to be able to be pushed into the removal hole 33 with a finger, it must be formed using a material having a certain degree of elasticity.
Specifically, the hardness is preferably from 50 to 70, and specifically, for example, styrene-butadiene, polyester, polyethylene, urethane, or other elastomers can be used, and the material is formed by injection molding. The above hardness is measured according to JIS K 6253 (Type A durometer).

[Effect of the invention]
In the sanitary tissue paper storage container 100 of the first embodiment described above, as shown in Figure 2, a female thread portion 11 is provided from the upper end on the inner surface of the side of the container body 1, and a male thread portion 211 that screws into the female thread portion 11 is provided on the outer surface of the side portion 21b of the lid body 2, which is slightly smaller in size than the inner diameter of the container body 1.
In such a sanitary tissue paper storage container 100, for example, a user can insert one finger of each hand into the finger insertion sections 21f, 21f and rotate the lid 2 to insert the lid 2 into the inside of the container body 1 as shown in Fig. 6, thereby adjusting the height from the bottom of the container body 1 to the lid 2. Therefore, as shown in Fig. 7, even if the height of the sanitary tissue paper P in the container body 1 is lowered by using a sheet, for example, and the removal hole 33 and the sanitary tissue paper P are separated from each other, the position of the lid 2 can be adjusted so that the removal hole 33 and the sanitary tissue paper P are closer to each other.
Therefore, even if the amount of sanitary thin paper P in the container body 1 decreases, the removal section 3 can easily maintain the opening, and the opening can be prevented from falling into the container body 1.

Furthermore, if the sanitary thin paper P is a wet sheet impregnated with a medicinal solution and the volume inside the container body 1 is larger than the volume of the sanitary thin paper P, the medicinal solution may evaporate when the sheet comes into contact with the air in this excess volume.
However, in the sanitary tissue paper storage container 100 of this embodiment, this excess volume can be reduced by lowering the height from the bottom of the container body 1 to the lid body 2 in accordance with the height of the sanitary tissue paper P in the container body 1 being lowered by using a sheet, so that even if the amount of sanitary tissue paper P, which is a wet sheet, in the container body 1 becomes low, evaporation of the medicinal solution can be suppressed.

[Second embodiment]
In the first embodiment as described above, a female thread portion 11 is provided at the upper end on the inner side of the side surface of the container body 1, and a male thread portion 211 that screws into the female thread portion 11 is provided on the outer surface of the side surface portion 21b. The lid body 2 is rotated using the finger insertion portion 21f to insert the lid body 2 into the container body 1, and the position of the sanitary tissue paper P can be adjusted so that the sanitary tissue paper P is closer to the removal hole 33. However, this is not limited to this, and a sanitary tissue paper storage container 100 according to a second embodiment as shown in Figure 8 may have a bottom female thread portion 12 provided at the lower end on the inner side of the side surface of the container body 1, and a mounting portion male thread portion 131 that screws into the bottom female thread portion 12 is provided on the outer surface of the side of the mounting portion 13, which is the bottom of the container body 1 and has an outer diameter of the top surface that is smaller than the inner diameter of the container body 1, and on which the sanitary tissue paper P is placed, and a mounting portion finger insertion portion 132, which is a recess into which a finger can be inserted, may be provided on the bottom portion on the outer surface side of the mounting portion 13.
Even with this configuration, the mounting portion 13 can be rotated using the mounting portion finger insertion portion 132 and inserted into the container body 1, thereby bringing the remaining sanitary tissue paper P in the container body 1 closer to the removal hole 33, thereby making it less likely that the mesh will collapse.

[Modification]
The present invention has been specifically described above based on the first and second embodiments, but the present invention is not limited to the contents of the above embodiments and can be modified without departing from the gist of the present invention.

For example, the finger insertion portion 21f shown in the first embodiment and the finger insertion portion 132 shown in the second embodiment are recesses formed in the lid body 21 or the mounting portion 13, but are not limited thereto, and may be a convex portion as long as it is possible to grip and rotate the lid body 21 or the mounting portion 13 inserted in the container body 1. The number of finger insertion portions is also not limited to two.
However, it is preferable that the placement portion finger insertion portion 132 be a recess from the viewpoint of stability when the container body 1 is placed.

In addition, in the first embodiment, the finger insertion portion 21f may not be provided, and the small lid 22 may be grasped with the removal portion 3 open to rotate the lid body 2 in the circumferential direction and insert it into the container body 1.

Also, as shown in Figures 2 and 7, or 8, when the sanitary tissue paper P is a wet wipe, in order to prevent gaps from occurring around the female threaded portion 11 and the male threaded portion 211, or the bottom female threaded portion 12 and the mounting portion male threaded portion 131, which are screwed together, a sealing member S that allows the lid body 2 or the mounting portion 13 to rotate while providing a seal when closed may be provided at the lower end of the male threaded portion 211 or the upper end of the mounting portion male threaded portion 131.

A stopper member may also be provided at the lower end of the female thread portion 11 or the upper end of the bottom female thread portion 12 to prevent unscrewing.

The removal section 3 may be detachable from the lid 2 or may be fixed thereto.
